We investigated the microstructural and fatigue characteristics on consolidated Japanese cedar called “ObiSugi (Cryptomeria japonicain)” fabricated by hot-pressing. Hot-press treatment was conducted at various conditions. Three point bending test, hardness test and plane bending fatigue test of consolidated wood were carried out to investigate mechanical properties. Flexural strength of consoli...

fatigue is recognized as one of the most disabling and frequent symptoms of multiple sclerosis (ms). amantadine appears to have some proven ability to alleviate the fatigue in ms. the aim of this study was to assess the efficacy of co-administration of amantadine and aspirin for the treatment of fatigue in multiple sclerosis. forty-five ambulatory patients aged 20–50 years with a diagnosis of m...

background: surface electromyography (semg) of muscles is a non-invasive tool that can be helpful in the assessment of muscle function and some motor control evaluations. a loss of force, known as muscle fatigue is accompanied by changes in muscle electrical activity. one of the most commonly used surface emg parameters which reflects paraspinal muscle fatigue during different tasks and positio...

This study aimed to investigate the effects of sleep deprivation on postural control, subjective fatigue assessment and psychomotor performance, and to assess the efficiency of an objective posturographic test as an indicator of mental fatigue. Postural sway using static posturography (Romberg's test), subjective fatigue assessment (Stanford Sleepiness Scale) and psychomotor performance (Sternb...

OBJECTIVES This study compared the cyclic fatigue resistance of nickel-titanium (NiTi) files obtained in a conventional test using a simulated canal with a newly developed method that allows the application of constant fatigue load conditions. MATERIALS AND METHODS ProFile and K3 files of #25/.06, #30/.06, and #40/.04 were selected. Two types of testing devices were built to test their fatigu...
